Voltify wants to reduce first-line support load with an LLM assistant that answers questions from our documentation and past resolved tickets. It must escalate gracefully to a human when confidence is low.
The work: build the retrieval pipeline over our docs (Markdown) and ticket history (Zendesk export), design the prompt and guardrails, and expose it behind a small API our web team can call. Evaluation matters: we want a test set and accuracy reporting, not vibes.
You will work directly with our support lead. Hourly, roughly 15 to 20 hours per week.

We are building a billing analytics product and need a customer-facing dashboard. The backend API already exists (REST, well documented); the work is the frontend plus a thin data layer.
Scope: overview page with MRR, churn and invoice status widgets, an invoices table with filtering and CSV export, and a settings page for notification preferences. Designs are ready in Figma with a small component library to follow.
We expect clean TypeScript, sensible component boundaries and at least basic test coverage on the data layer. Deployment is on Vercel, preview builds per PR are already configured.

An existing React Native app (news reader for a media client) needs two features: robust offline reading and push notifications with topic subscriptions.
Offline mode should download the day's articles and images for flight mode reading, with sensible cache eviction. Push uses Firebase Cloud Messaging; the backend endpoints exist already. The codebase is TypeScript, well tested, around 30k lines.
We will onboard you with a walkthrough call and a staging environment. Please mention similar offline-sync work in your proposal.

Northwind Labs is building inventory software for small warehouses. We need an experienced backend engineer to design and implement the core REST API: items, locations, stock movements, low-stock alerts and an audit trail.
Stack is Node.js with TypeScript and PostgreSQL. You will own the schema design, migrations and API implementation; our team handles the frontend. Expect roughly 25 endpoints, role-based access and webhook notifications for stock events.
This is an hourly engagement with weekly demos. Long-term follow-up work is likely for the right person.

Our current marketing site was designed in a weekend two years ago and it shows. We need a redesign concept in Figma for 6 pages: home, product, pricing, about, blog index and a blog article template.
We have a rough brand direction (colors, logo) but are open to evolution. Deliverables are polished Figma frames for desktop and mobile plus a small style guide so our in-house developer can implement without guessing.
Please include one or two relevant portfolio pieces in your proposal. We value clear typography and restraint over flashy effects.

Harbor Analytics needs a data pipeline for a logistics client: ingest daily sales exports (CSV over SFTP), load them into PostgreSQL, model the data and build a reporting dashboard the client's ops team can use.
The dashboard should cover revenue by lane, on-time delivery rates and weekly trends. We are open to your tooling suggestions for the dashboard layer as long as it is maintainable and self-hosted.
Documentation and a handover call are part of the scope. Data volumes are modest, low millions of rows.

Bluepeak Media is building a fitness MVP for a consumer brand client. The app tracks workouts, streaks and a simple social feed. We have full designs and a Firebase backend already set up by another contractor.
Scope for the MVP: onboarding, workout logging with templates, streak calendar, push notifications and the feed (read-only for v1). Both iOS and Android from one Flutter codebase.
We care about smooth animations and offline tolerance; gym basements have terrible reception. Store submission support is part of the final milestone.

We run a personal finance blog for a fintech client and need 12 articles over the next six weeks. Topics are already researched and outlined: budgeting apps, emergency funds, index investing basics and similar evergreen subjects.
Each article is 1200 to 1500 words, written for beginners, with sources linked and a short meta description. Our editor reviews everything, so expect one revision round per piece.
Native-level English required. Please share two writing samples in a similar niche.

Plum Street Studio runs a homeware Shopify store with about 800 products. Organic traffic has been flat for a year and we suspect technical issues: duplicate collection pages, slow templates and a messy internal linking structure.
We want a full technical audit with a prioritized fix list: crawlability, index coverage, structured data, page speed and internal links. Deliverable is a working document our developer can execute on, plus a 1-hour walkthrough call.
Bonus points if you have Shopify-specific experience and can name the usual template pitfalls.

We currently run six services on plain EC2 with a homegrown deploy script that everyone is afraid to touch. We want to move to EKS with proper CI/CD, secrets management and observability.
Scope: cluster setup with Terraform, containerize the remaining two services, set up GitHub Actions pipelines, Prometheus and Grafana, and migrate staging first, then production with a documented rollback plan.
You will pair with our two backend engineers so knowledge stays in the team. Hourly engagement, estimated 6 weeks at 20 to 30 hours per week.
